- Not on the record in Spain, Mexico City, Argentina, Puerto Rico, England and Wales, Canada, Ireland, New Zealand, Scotland and Poland: those registries withhold small counts, so rare uses may sit below their floors.
- Not on the Chile record: nametree keeps spellings that reached 5 registrations in some year, so rarer uses are not shown.
- Not on the Montevideo record for 1940 to 2011: that registry withholds nothing, so this spelling was not given there in those years.
- Not on the France record: nametree keeps spellings that reached 20 births in some year, so rarer uses are not shown.
- Not on the South Australia record for 1944 to 2017: that registry withholds nothing, so this spelling was not given there in those years.
- Not on the Austria record for 1984 to 2025: Statistik Austria publishes every first name down to a single birth, so this name was not given there in those years (before 2010 the record covers babies with Austrian citizenship only).
